tor Motor, of which the following is a full,

clear, and exact description.

Among the principal objects which the present invention has in View are to provide a self-propelling motor for clearing the side walls of pipes, conduits and other passages;

to utilize the propelling force of'a column of fluid for operating, a rotary element adapted to clean or remove obstructions in subterranean or other fluid-filled passages; and to provide suitable means for removing the encrusta-tions oradhesions fromboiler and other tubes.

Drawings.

Figure 1 is aside elevation partly in section of a motor constructed and arranged in accordance with the present invention, the

same being shown as actively mounted on a hose pipe;

Figure 2 1s a cross section of the same, the

section being taken on the line in Figure 1.

As seen in the drawings the motor has amushroom-like head 7 and a series of openings 8 in the overhanging portion of the head 7.

ranged to provide curved passageway from the tubular neck 9 to the said openings 8..

This is accomplished by providing the interior with an inverted crest 10 the apex whereof is coincident with the axis of the neck 9. From the point of the crest 10 the inner wall of the head 7 is curved through the openings 8, the purpose of the curved wall being to return the fluid passing through the neck 9 in paths parallel to t direction.

The neck 9 is preferably rigid on a coupler 11, which is screw threaded and connected to a hose pipe 12.

Rotatably mounted on the neck 9 is a col lar 13. The collar 13 shown in the accompanying drawings has a series of scraper blades 14, the blades 14; being disposed in angular relation to the axis of the neck 9 to present inturned surfaces in the path of the fluid as the same is emitted from the open ings 8 in the head 7.

The interior of the head 7 is ar-' ne axis of the neck 9 but flowing in a reversed The blades 14 are preferably constructedof thin fiatresilient metal, such as steel.

The blades are preferably disposed in tiers, each'tier extending slightly beyond the preceding or advanced tier, thereby offering successively a larger area for operation.- The rotary brush thus formed hasbeerr found efiicacious 1n cleansing boiler tubes and similar conduits and for removing the scale or enc-rustation formed thereon.-

lin the operation of the motor constructed and arranged as herein disclosed the fluid under pressure is delivered to the interior of the head 7 through which it flows smoothly, being parted in the center by the crest 10 and carried by the wall to the various openings 8, to be there emitted for im' pingement upon the blades l t. The blades 14 may be multiplied or subtracted from as desired to increase or diminish the effectiveness of the impacts which they exert upon the surface being cleared or cleansed by them.

It will be understood that the speed with which the collar 13 is rotated is very great,

due to the slight resistance offeredto the flow of the fluid from the openings 8, and to the constancy of the flow of the said fluid.

lVhile I have shown and described the motor as employing the collar 13 having straight blades 14; for dislodging or removing scale or other deposit from tubes or other conduits, the collar and the blades may be substituted by other rotary supporting member and inclined vanes arranged to receive the streams of fluid emitted from the openings 8 and directed upon the inclined surfaces of the said vanes.

' It is also evident that the flow of the fluid from the openings 8 past'the blades 14 operate by pressure upon the surrounding medium to propel the motor forward, in the line of its work.

It will also be understood thatany suitable fluid having pressure imposed thereon by any suit-able means may be employed for operating the present motor.

Claims.

1. An apparatus as characterized comprising a hollow head having an unbroken front wall, and a rear wall having a centrally disposed receiving opening, and a series of delivery openings surrounding said receiving openings for delivering the fluid from said head in lines approximately parallel to the fluid being delivered to said head; and rotative means disposed in the path of fluid delivered from said delivery openings to be rotated thereby.

2. An apparatus as characterized comprising a hollow head having an unbroken front wall,- and a rear wall having a centrally disposed receiving open ing, and ass 'ries of delivery openlngs surrounding said with the rotation of said rotary member.

3. An apparatus as characterized com-V prising a hollow head having an unbroken front wall, and a. rear wall having a centrally disposed. receiving opening,- and a series, of delivery openingssurrounding said receiving openings for delivering the fluid fromsaid head in lines approximately parallel to the fluid being delivered to said head rotative means disposed in the path of fluid delivered from said delivery openings to'be rotated thereby; and means carried by said rotative' member for performing a desired function in paths concentric. with; the rota tion of said rotary member, said means embodying a series of abrasive members I mounted upon, and extending outward from said rotary member. I

4. An apparatus as characterized com prising a hollow head having an unbroken front wall, and a rear wall having centrally disposed receiving opening, and a se ries of delivery (mailings surroundingsaid receiving openings for'delivering the fluid from sald head in lines approximately par; allel to the fluid being delivered to said head; rotative means disposed in the path of fluid delivered from saiddelivery openings to be rotated thereby; and means carried by said rotative member for performing a desired function in paths concentric with the rotationof said rotary member, said means embodying a series of abrasive members mounted upon, and extending outward,

from said rotary member, said blades being disposed in progressively increasing radial dimensions from said head backward.

5. An apparatus as characterized com prising a head embodying a hollow chamber, and arearwardiy' extended tubular neck for delivering fluid to said chamber; and an unbroken front wall having an inwardly-extended conlcal pro ection the apexwhereof coincides with the axis of said neck; a seriesv of rearwardly opening apertures fordeliv-- ering the cOIltBIltsOf said chamber in paths approximately parallel to said neck; and a rotary abrasive member, said member em? bodying a collar rotatively 1 permanently mounted on said neck and having a series of inclined blades adapted to be deflected by the fluid delivered from said head and abrasivemembers extended beyond the path of said fluid for operating on the side walls of a conduit through which said apparatus is moved. I i i 7. An apparatus as characterized comprising a head embodying a hollow chamber and a rearwardly extended tubular neck for delivering fluid to said chamber; and an unbroken front wall having an inwardlyem tended conical projection the apex whereof coincides with the axis of said neck; a series of rearwardly opening apertures for delivering the contents, ofsaid chamber in paths approximately parallel tos'aid neck; and a rotary abrasive member, said inember' enibodylng acollar 'rotatively mounted on said neck and having a series of inclinedblacles adapted to be deflected by the fluid delivered from said head; and abrasive members as tended beyond the path of said fluid for operating on the side walls of a conduit through which said apparatus is moved, said abrasive members being integral with and extended from saidblades.
